How the Elite Steam Humidifier Works

Elite Steam is an electrode humidifier. It produces steam for humidification by passing electric current through the water between metal electrodes in the plastic steam generator cylinder. There are no heating elements. Steam output is directly proportional to the conductivity of the water, and the amount of electrode immersed in the water.

The Steam Cylinder is the engine of the humidifier. As the humidifier operates and water is evaporated and minerals are left behind. Much of these minerals are removed through the cylinder drain. Some are deposited on the walls of the cylinder and the cylinder electrodes. When a lower section of the electrodes develop a thick coating, the water level is raised to expose clean electrode surface.

Eventually minerals cover the electrodes’ entire length with a thick coating and little electrical current can pass between them resulting in poor steam output. The humidifier can sense the low amperage and will display the E6 Cylinder Exhausted error code. There are several factors that influence cylinder life

Humidity Load and Cylinder Life

Humidity load demands have an effect on cylinder life. Normal installations where humidity capacity is properly sized require only intermittent periods where full humidifier capacity is required. This allows the water level in the cylinder to be increased only as electrode segments become insulated.

This tends to maximize cylinder life. Extraordinary installations that require constant operation at full capacity reduce cylinder life. The water level in the cylinder is, on average, much higher, and the electrodes become completely insulated more quickly. Installations like this may result in cylinder life of less than 1000 hours.

Maximum Steam Production

Another factor affecting cylinder life is the maximum production setting. A higher production rate will result in a shorter cylinder life. For this reason DS-25 and RS-25 units are preset from the factory at 70%. Further reductions in Maximum Steam Production will extend cylinder life.

Check Water Quality

If water conditions are outside the parameters shown above or those shown in the Installation Manual, do not install the unit. Contact the factory for technical support.

  • 1. Softened water as this will lead to foam, electrode corrosion and greatly shortened cylinder life.
  • 2. Water containing disinfectants or corrosion inhibitors, as these are potential irritants.
  • 3. Industrial water, boiler water or water from cooling circuits.
  • 4. Any potential chemically or bacteriologically contaminated water.
  • 5. Heated water.
  • 6. Water with silica deposits.

Structures Under Construction

In high end construction projects, humidification is often required while the structure is being finished. Humidification is necessary to protect and stabilize wood floors, trim and decoration. Humidification load, however, in an unfinished structure may be five to eight times higher than when finished. Elite Steam humidifiers may be operated while construction is underway but, reduced cylinder life is to be expected and budgeted for. Good practice dictates that the steam cylinders also be replaced once the project is complete.

Why add humidity?

When cold, dry air enters your home and is warmed to room temperature, the relative humidity in the average house can drop to as little as 5%. Compare that to the average 25% relative humidity of the Sahara Desert and you can understand why the air inside your home can seriously affect your health and comfort.

Since various studies have estimated that most people spend as much as 90% of their time at home indoors, there's reason to be concerned about indoor air quality.

Air quality is only a concern outdoors, isn’t it?
Not true! The air inside your home can be even more of a concern to your health and comfort, especially in the winter.
